A satellite is to be launched from the surface of the earth. Name the factors on which the escape velocity of the satellite depends.

Open in App

Solution

Escape velocity is given by :
$v = \sqrt{\frac{2 G M}{R}} = \sqrt{2 g R}$
Escape velocity depends on
i) Radius of the earth $R$
ii) Acceleration due to gravity $g$ .
